It wouldn't mean no victories unless the two of aren't working together when you play together.
Edit:
It looks like you both are just really new at the game and suck because of that. I'm not holding it against you, since I think the new player experience is pretty terrible at getting players started, but I don't think it's a problem with matchmaking. Matchmaking seems to be doing it's best to match you with equally clueless players.
Both of you: Heal + Teleport isn't the winning combo of Summoner Spells, and Thunderlords Decree isn't the best Mastery for every champion. I recommend looking up some guides on your favorite champions and seeing what other players build on them, because your builds aren't quite as effective as you're thinking they are.
Victory88: Windspeakers Blessing is far better on Soraka than Thunderlords, since it makes her healing even stronger. Buy
early and use it to give your team more information about where the enemy is. Normally supports run
and
as their summoner spells, letting them reduce the damage of enemies, get into situations to save allies, and out of dangerous situations.
MoreVictory88: Use
. It's free, you've got one every game, but you've got several recent games where you haven't placing a single ward. That's frankly unacceptable for anyone past level 10. In general you want
as a Summoner Spell every game, largely for the added safety it gives you. Who cares about getting to a lane a little faster when you can avoid dying or get more kills with Flash.
